TENSIONING MEANS FOR TA'I'TING THREAD.

Application filed February 15, 1927. Serial No. 168,422.

This invention relates to thread holding devlces and particularly tomeans for holdmg a thread and applying tension thereto while tatting.

In tatting with two threads, it is always necessary to hold the secondor chain thread necessary to obtain the proper tension on this thread bywinding the thread about the fourth finger after opening the fingerswith the thread passed over the outside of the fingers.

This means that as the thread is used, the fingers are gradually drawnto-.

gether, thus in a way paying out the thread as it is used, and whenslack has all been taken up in this manner, then the work has to bestopped while the thread is unwound from the fourth finger, the fingersof the hand again opened, and the thread again wound about the fourthfinger. This continual stoppage in order to wind and unwind the threadabout the fourth finger is inconvenient and takes up considerable-time.The ob ert of my lnventlon is to provide means for exerting a constanttension upon the thread, whichineans is in the form of a ring adapted tobe supported upon the fourth finger of the left hand, through which ringthe thread is passed, this ring having spring means whereby tension issecured and friction exerted upon the thread at all times.

My invention is illustrated in the accompanying drawings wherein Figure1 is a top plan view of a ring having my friction. device carriedthereby;

lfi 2 a side elevation thereof;

is an edge elevation thereof.

Referring to these drawings it will he soon that the ring 10 has asolid, straight, and transversely extending portion 11 thicker than thethickness of the ring 10 and cut away so as to provide a longitudinallyextending ledge 12. Held in place against the face 13 of the portion 11by means of a rivet 14 is a leaf spring 15, the middle of this springbeing outwardly bowed and the extremity of the spring extending towardthe face 13 and then being outwardly bent.

bears cone spring is provided wit-h a small thread opening 17.

In the use of this device, the thread is passed through the hole 17 andsnapped under the portion 16 of the spring. The ring is then placed onthe fourth finger and thereafter no more attention need be given to thethread as the thread will always be frictionally engaged by the portion16 of the spring. The tension is maintained 011 the thread at all timesand by simply opening the fingers of the hand around which the threadhas been passed, the thread may be caused to slip through thistensioning device. -Therefore, as thread is required, it is onlynecessary to open the fingers of the hand, closing the fingers as thethread is used, and then again opening the fingers intermittently as thethread is needed.

It will be noted that the spring 15 bears against the side faces orlateral faces of the portion 11 and that the spring operates in a planeat right angles to the plane of the ring.

There is no tendency, therefore, under these circumstances for a threadto pull out by any lateral pull, as would be the case did the.

spring operate in the same plane as the ring itself.

It is to be understood, of course, thatthe ring may be made in varioussizes to fit different fingers and that many modifications the ring, aleaf spring mounted upon the i straight portion, the spring flexing in aplane at right angles to the plane of the ring, the spring beingoutwardly bowed at its middle and having contact with the straightportion of the ring at its extremity, the bowed portion of the springbeing perforated for the passage of a thread.

2. Means for frictionally engaging a thread when tatting comprising aring having a straight portion, this portion being cut away at onecorner to form a face extending inward from the lateral face of the ringand a face extending outward from the first named face in a planeparallel to the plane of the ring, a bowed leaf spring mounted at oneend against the last named face and hearing at its other end againstthelast na1ned face, the bowed portion of the spring remote from thefree end thereof having a perforation.

In testimony whereof I hereunto affix my signature.
